Abstract: 수평축풍력터빈로터용블레이드(20)는반경방향-외측, 에너지-추출부분(32) 및반경방향-내측, 환기부분(30)을포함한다. 반경방향-내측환기부분(30)은, 종래로터설계로부터의후류(wake)와비교하여더 많은운동에너지를담고있도록, 사용중에로터후류의중앙영역(34)을환기하도록형상지워진다. 후류의중심(34)에서증가된바람유동속도는추가적인전단응력을생성하며, 증가된후류확산을일으키는대응하는난류확대(development)를갖는다.
Abstract translation: 用于水平轴风力涡轮机转子的叶片20包括径向向外的能量提取部分32和径向向内的通风部分30。 径向内部通风部分30被成形为在使用期间排出转子尾流的中心区域34,以便包含更多的动能以及来自常规转子设计的尾流。 尾流中心34处增加的风速产生额外的剪切应力,并具有相应的湍流发展,导致尾流扩散增加。

Abstract: A blade 20 for a horizontal-axis wind turbine rotor comprises a radially-outer, energy-extraction portion 32 and a radially-inner, ventilation portion 30. The radially-inner ventilation portion 30 is shaped to ventilate a central area 34 of a wake of the rotor during use such that it contains more kinetic energy compared to the wake from a conventional rotor design. The increased wind flow velocity at the centre 34 of the wake generates additional shear stresses, with corresponding turbulence development, which gives rise to increased wake diffusion.
